I have found all my roles on there and all but one through the one click easy apply. That’s the only benefits - good (maybe best in the USA) pool of jobs and mostly reasonable application process. I ignore the posts, limit visibility and only connect with people I’ve met or worked with directly.
It truly sucks though, full of spammy engagement bait and bad recruiters. It’s tough, but personally I think having an account is worth it even if I ignore until it’s time for another job hunt.
Arch is incredibly user friendly - gets completely out of the way of the user so they can do exactly what they want how they want.
Arch is not very beginner friendly - depending on what you consider a beginner, it will not hold your hand except for the install process where it provides a walkthrough script. If you have configured Linux before it will be familiar but you may have to read documentation. It’s not designed to be difficult, but it is designed for people who know why the choices they are making matter. If you do not understand then there will be a gap and that may feel a bit frustrating, but it is on you to bridge that gap.
